球面四元三角网的三拓扑数计算

Computation of Three Topological Numbers on Spherical Quaternary Triangular Mesh

    摘要
  • 摘要: 讨论了任意球面三角格网p的三拓扑数计算。任意球面三角格网p的三拓扑数是指和该球面三角格网互为三邻近的目标球面三角格网的个数,它是讨论球面栅格区域局部拓扑不变量的重要参数,也是描述和推断球面栅格拓扑关系首先要解决的问题。

     

    Abstract: Spherical QTM(quaternary triangular mesh) is efficient to deal with the global data because of its advantages of multi-resolution and hierarchy.Computation of three topological numbers on spherical QTM is presented.Three topological numbers of any triangles is the numbers of 3-neighbor to the triangle,which is the base of computing topological relation of Spherical QTM.
